[SPARK-9733][SQL] Improve explain message for data source scan node.
All data sources show up as "PhysicalRDD" in physical plan explain. It'd be
better if we can show the name of the data source.
Without this patch:
```
== Physical Plan ==
NewAggregate with UnsafeHybridAggregationIterator ArrayBuffer(date#0,
cat#1) ArrayBuffer((sum(CAST((CAST(count#2, IntegerType) + 1),
LongType))2,mode=Final,isDistinct=false))
Exchange hashpartitioning(date#0,cat#1)
NewAggregate with UnsafeHybridAggregationIterator ArrayBuffer(date#0,
cat#1) ArrayBuffer((sum(CAST((CAST(count#2, IntegerType) + 1),
LongType))2,mode=Partial,isDistinct=false))
PhysicalRDD [date#0,cat#1,count#2], MapPartitionsRDD[3] at
```
With this patch:
```
== Physical Plan ==
TungstenAggregate(key=[date#0,cat#1], value=[(sum(CAST((CAST(count#2,
IntegerType) + 1), LongType)),mode=Final,isDistinct=false)]
Exchange hashpartitioning(date#0,cat#1)
TungstenAggregate(key=[date#0,cat#1], value=[(sum(CAST((CAST(count#2,
IntegerType) + 1), LongType)),mode=Partial,isDistinct=false)]
ConvertToUnsafe
Scan
ParquetRelation[file:/scratch/rxin/spark/sales4][date#0,cat#1,count#2]
```
